## Symptoms

- The Neighbor Advertisement correctly advertises the ClusterXL VIP IPv6 address and MAC address, but the Router Advertisement advertises the local interface IPv6 address and the local interface MAC address.

## Cause

IPv6 Router Discovery is not supported on ClutserXL for versions lower than R80.40. Refer to [sk102369](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk102369).
